“On Monday, researchers will tell the world’s largest annual meeting of neuroscientists that some scientists working on organoids are “perilously close” to crossing the ethical line, while others may already have done so by creating sentient lumps of brain in the lab. “If there’s even a possibility of the organoid being sentient, we could be crossing that line,” said Elan Ohayon, the director of the Green Neuroscience Laboratory in San Diego, California. “We don’t want people doing research where there is potential for something to suffer.””
